Separation Energies • The neutron and proton separation energies are the equivalent of the ionisation energies in atomic physics. • The neutron separation energy S, is the amount of energy needed to remove a neutron from a nucleus (XN, equal to the difference in binding energies between X and Sn = = B (XN) - B (1X-1) (A-1) [m(-¹XN-1)-m (xx)+mn]ª² X(N-1): ⚫ The proton separation energy S, is similarly defined as the energy to remove a proton: Sp = = B (XN) - B (XN) [m (XN) -m (XN)+m(H)] c² Nuclide [6] Z N Isotopic mass (u)[7] [n 1] 2He[n 6] 202.015894(2) 3 He[n 7] 2 1 3.01602932265(22) 4 He[n 7] 2 2 4.00260325413(6) 5 не 2 3 5.012057(21) He [n 9] 2 4 6.01888589(6) 7.
